No category of real estate is more mythologised or more misunderstood. Private islands are scarce, the transaction mechanics are unlike anything else in property, and the price spread is wider than in any other segment: a Finnish archipelago island can be had for the price of a car, while the most expensive listing in the Caribbean asks $125 million.
The distinction most coverage misses is between islands genuinely on the market and islands that appear on rankings because they once were. Trophy islands trade rarely and quietly, they are frequently withdrawn and relisted at revised prices, and a name appearing on ten for sale lists may have changed hands years ago.
What follows are ten assets genuinely available in the current market cycle, at the prices they were marketed. Verify with the named brokerage before you plan anything.

1. Blue Island, Exuma Cays: about $125 million
The Caribbean's ceiling. Blue Island spans 700 acres with more than three miles of coastline, elevations reaching around 100 feet and multiple internal lagoons.
What separates it from every other island in the region is infrastructure most sovereign territories would recognise: a 5,700 foot asphalt airstrip capable of receiving private jets directly from the United States or Europe, its own customs and immigration facilities, a main house, staff housing and roughly four miles of internal roads.
The immigration post is the detail that matters. On almost every private island on earth, arrival means clearing customs on the mainland first. Blue Island removes that step, which is a functional difference rather than a marketing one. It has been marketed between $75 million and $125 million across its listing history, so confirm current availability directly.
2. Tarpon Island, Palm Beach: sold at $150 million
The most instructive transaction in the private island market, and the most extreme price per acre ever recorded.
In May 2024 a 2.3 acre island in the Palm Beach Intracoastal Waterway sold for $150 million to a buyer using a Delaware LLC whose identity stayed undisclosed for days. The seller had paid $85 million for the same parcel three years earlier, then developed it.
That is roughly $65 million per acre, against Caribbean trophy islands trading closer to $150,000 to $200,000 per acre. What you buy in Palm Beach is not land. It is a fully built, fully serviced, fully connected private island four minutes from a mainland with hospitals, staff, provisioning and an international airport. That premium, roughly 300 times the Caribbean rate, is the price of removing every operational problem described later in this article.
3. Ronde Island, Grenada: marketed near $100 million
One of the largest privately held island opportunities in the Caribbean, lying between Grenada and Carriacou across roughly 2,000 acres. Its value case rests on scale and development potential rather than existing infrastructure, and it has historically been positioned for resort or master planned development rather than single family use.
Grenada is also the only Caribbean nation combining citizenship by investment with both visa free China access and United States E-2 treaty eligibility, which gives a purchase there a secondary strategic dimension.
4. Pumpkin Key, Florida Keys: $75 million to $95 million
A perennial fixture on trophy property lists and the most practically usable large island in North America. Pumpkin Key sits minutes by boat from the Ocean Reef Club, giving owners a full private club ecosystem including dining, golf, marina services and an airstrip without having to build any of it.
The 26 acre island carries a main residence, guest cottages, staff quarters, a helipad, a 20 slip marina and approved homesites. It has been marketed most prominently at $95 million and more recently around $75 million.
5. A 381 acre island, Turks and Caicos: about $75 million
Turks and Caicos combines the strongest legal framework in the Caribbean for foreign ownership with genuine tourism demand and no direct taxation. A 381 acre offering at $75 million works out at roughly $197,000 per acre, close to the regional benchmark for large undeveloped trophy islands.
Islands at this scale are almost always acquired with a development thesis rather than a residential one, given the ratio of land to what any single family can meaningfully occupy.
6. A 376 acre island, St Vincent and the Grenadines: about $54 million
The Grenadines are the Caribbean's yachting heartland, and this is where price per acre starts to look reasonable next to the Bahamas and Florida. At around $144,000 per acre, this is the value end of the serious trophy segment. The trade off is access: the Grenadines require more connections than the Exumas, which is precisely why the acreage is cheaper.
7. North Eleuthera estate island, Bahamas: $45 million
A different proposition from the raw acreage plays above. This asset carries deep water anchorage, direct airstrip access and existing resort development approvals, which is the combination that determines whether an island can be commercialised or only inhabited.
At this level the relevant benchmark is not other islands. It is branded resort real estate, because that is what the buyer pool compares it against. Bahamian ownership is freehold, with government registration required for parcels above two acres.
8. Haines Cay, Bahamas: about $37.9 million
Three hundred acres of undeveloped land with white powder beaches, creeks, mangroves and bluffs. The sale has included a developer's package on Great Harbour Cay, 600 feet across a creek, which effectively bundles a mainland service base with the island.
That structure solves the single largest operational problem in island ownership: where the staff live, where supplies land, and where the boats are maintained when the weather closes in.
9. Katafanga Island, Fiji: 225 acres
Katafanga brings substantial groundwork already completed, which in the South Pacific is worth more than the land itself. It carries villa construction, an airstrip, a water reservoir and a road circling the island, and it sits within a 5,000 acre natural lagoon in the Lau Group.
The critical due diligence point in Fiji is title. Freehold covers only around 8 per cent of Fijian land. Most island transactions are leasehold, and a leasehold island with 50 years remaining is a fundamentally different asset from a freehold island with identical beaches.
10. Wavi Island, Fiji: from about $15 million
The clearest entry point into genuine island ownership in the Pacific. Wavi sits near Savusavu Airport on Vanua Levu with 27 acres of freehold land, an operational guest pool, bar, tennis court and marina, plus nineteen vacant development plots. It went to international auction in December 2025.
Freehold designation makes it genuinely rare. Combined with proximity to a functioning airport, it is arguably the most practical island here for a buyer who intends to use it rather than develop it.
What islands cost outside the trophy tier
The category is not exclusively a billionaire's game, and the price floor is far lower than most people assume.
| Region | Entry point |
|---|---|
| Finland and Sweden | From around EUR 34,000 with existing cabins |
| Canada (Nova Scotia) | Regularly under $100,000 |
| Ireland | From around EUR 120,000 |
| Belize and Nicaragua | From roughly $225,000 for small cays |
| Bahamas | From around $500,000 |
| Indonesia | From around $900,000 |
| Croatia and Italy | From around EUR 1.5 million |
| Fiji | From around $1.7 million |
| Greece and French Polynesia | From around EUR 2.2 million |
The Caribbean accounts for over 40 per cent of all private island listings globally, with the Bahamas alone holding hundreds of islands and cays in private hands.
The listing price is roughly half your actual spend
This is the number that changes every buyer's arithmetic. Analysis across multiple jurisdictions consistently finds that buyers of undeveloped islands spend approximately 1.8 times the listing price before the island is habitable.
Power generation, desalination or water catchment, waste treatment, dock and seawall construction, staff accommodation, a boat fleet, communications, and construction logistics where every bag of cement arrives by barge. A $10 million island is an $18 million project, and the timeline is measured in years rather than months.
The islands commanding extreme premiums, Palm Beach at $65 million per acre or Blue Island with its own airstrip and customs post, are priced that way precisely because someone already absorbed this cost.
Ownership structure varies more than price
- Freehold available: the Bahamas (registration required above two acres), Italy, Turks and Caicos, Panama, Canada, Finland and most United States states.
- Freehold rare: Fiji, where freehold covers around 8 per cent of land. Verify title before anything else.
- Foreign purchase restricted: French Polynesia restricts foreign residential island purchase, and Brazil requires government approval for coastal property.
- Leasehold only: Vanuatu and Tonga operate long term leases. A 2026 clarification confirmed foreign leases there do not include adjacent marine areas, meaning you may hold the land without holding the water around it.
- No foreign land ownership at all: the Philippines, Indonesia and Thailand. All foreign holdings run through leases or corporate vehicles, and prices per acre are among the highest globally because of hotel developer demand.
Panama offers the most straightforward foreign ownership process in the Americas, with the same property rights as citizens and no coastal restrictions.
Islands are illiquid in a way no other asset is
Private islands do not perform well at auction. Innocence Island in the Bahamas, listed at $55 million in 2013, sold at auction for $17 million, a $38 million discount, with bidding opening at $8 million and stalling within minutes. The seller was terminally ill and wanted cash rather than the asset for his children. The buyer pool for a $20 million island is small, geographically scattered and physically difficult to bring to a viewing.
The counter example is instructive. Richard Branson paid approximately $180,000 for Necker Island in 1979, and its estimated current value is around $100 million. But Branson did not simply hold land. He built a brand around it: a Balinese style villa, a kitesurfing culture and a guest list of heads of state. The appreciation followed the story, not the acreage.
Buy an island as a use asset with a very long horizon. Do not buy one expecting to exit on your own timetable.
Frequently asked questions
Can you actually buy a private island?
Yes. There are typically hundreds on the open market worldwide at any moment, from under EUR 40,000 in Finland to more than $125 million in the Bahamas. The main constraint is jurisdiction, not availability.
How much does a private island cost?
Entry level islands in Nova Scotia and Finland start below $100,000, small undeveloped cays in Belize and Nicaragua around $225,000, and Caribbean trophy islands from roughly $15 million to $125 million. Add around 1.8 times the purchase price to make an undeveloped island habitable.
What is the most expensive private island for sale?
Blue Island in the Bahamas at approximately $125 million for 700 acres, with a 5,700 foot jet airstrip and its own customs and immigration facilities.
Which countries let foreigners buy islands outright?
The Bahamas, Turks and Caicos, Italy, Canada, Panama, Finland and most of the United States. Fiji offers freehold on only around 8 per cent of its land, and the Philippines, Indonesia and Thailand prohibit foreign land ownership entirely.
Do you own the water around a private island?
Generally no. Marine areas are almost always sovereign, and a 2026 clarification confirmed that foreign leases in Vanuatu and Tonga do not include adjacent marine areas. Anchorage, mooring and reef rights are separate questions to settle before purchase.
Are private islands a good investment?
They are illiquid, expensive to hold and difficult to exit. They have performed exceptionally for owners who developed them and built demand around them, and poorly for owners who needed to sell quickly.
What is the cheapest private island you can buy?
Archipelago islands in Finland and Sweden from around EUR 34,000, often with an existing cabin, and Canadian lake and coastal islands regularly under $100,000.
Listing prices reflect the most recent publicly available figures and change frequently. Islands named here may have sold, been withdrawn or been repriced. Verify current status and title with the listing brokerage and local counsel before acting.
